A career .298 hitter and three-time Gold Glover, LeMahieu has spent the majority of his career with the Rockies. However, LeMahieu's career home/away splits indicate his hitting numbers could be inflated by playing the majority of his games at Colorado's Coors Field: an .835 OPS and .330 BA at home, a .673 OPS and .264 BA on the road.

Gonzalez has spent his entire seven-year career with the Astros, winning the World Series with Houston in 2017. As well as possessing a decent bat, he's a versatile defender: in 2018 alone, he played double-digit games as a left fielder, shortstop, second baseman and first baseman.

Harrison, like Gonzalez, has spent his entire career thus far with one team, going to two All-Star Games as a Pittsburgh Pirate. He's coming off a down year, hitting .250 in 2018 with eight home runs and 37 runs batted in just 97 games.

Wilmer Difo and a healthy Howie Kendrick would have likely been the platoon at second base, with top infield prospect Carter Kieboom waiting in the wings, but it now appears the Nats have plans to upgrade.
